Jerin John updated CALCITE-5978:
--------------------------------
Description:
Add support for [REGEXP_INSTR
|https://cloud.google.com/bigquery/docs/reference/standard-sql/string_functions#regexp_instr]
function from BigQuery.
*{{REGEXP_INSTR(string, regexp [, position [, occurrence [,
occurrence_position]]])}}*
Returns the lowest 1-based position of the substring in {{string}} that matches
the {{{}regexp{}}}, Returns 0 if there is no match
* If {{position}} is specified, the search starts at this position in
{{{}string{}}}, otherwise it starts at the beginning of {{{}string{}}}.
* If {{occurrence}} is specified, the search returns index for the specific
occurrence of the {{regexp}} in value, otherwise returns the first match.
* If {{occurrence_position}} is specified as 1, returns the end index of
substring + 1 (default 0 returns start index of match)
Example:
{{SELECT REGEXP_INSTR("abcadcabcaecghi", "adc") as result;}}
+--------+
| result |
+--------+
| 4 |
